Super easy to install. I read some other reviews saying that it doesn't mount securely, but I think they must have put it on upside down (it is possible to do this if you don't pay close attention to the way that the clip works).

It has several flashing patterns with the 5 LED's, but I think it's safest to either use the steady mode or the all on/all off mode, so there's not much benefit to the other patterns.

I would not recommend this light for anyone who is expecting it to take much physical abuse, but if you are just looking for something simple that will be easy to mount and keep you safer on the roads the price can't be beat.

My wife has a Nashbar tail light and I thought I was buying the same thing but apparently the old one has been replaced. This light works fine and has more than enough options for flashing modes, but the LEDs are not as bright as the previous model. My saddle has reflective material on it as well as the back of my shoes, and there's a reflector on the bike as well, but if I had to do it over again I would probably spend a little more for a brighter light.

This is about all you need for a rear light. It has more flashing options then I need but that's ok.The quality seems in par with some of the brand name options. I see there's a rubber gasket/seal around the two pieces, this is important.The bracket is simple.
